DotImaging.IO

Unified stream-like platform-abstract API for IO video access: web-camera support, various video-format reading / writing, image-directory reader. Image loading/saving (file or in-memory).

• image loading / saving:

  Bgr[,] image = ImageIO.LoadColor("sample.jpg"); //load Bgr color image Gray[,] hdrImage = (ImageIO.LoadUnchanged("hdrImage.png") as Image<Gray>).Clone(); //load HDR grayscale (or any other) image image.Save("image.png");

• image in-memory encoding / decoding

  Bgr[,] bgrIm = ImageIO.LoadColor("sample.jpg"); byte[] encodedBgr = bgrIm.EncodeAsJpeg(); //or png, bmp Bgr[,] decodedBgr = encodedBgr.DecodeAsColorImage();

• media (camera, video, image-directory) capture:

  ImageStreamReader reader = new CameraCapture(); //use specific class for device-specific properties (e.g. exposure, image name, ...) reader.Open();

  //read single frame var frame = reader.Read().ToBgr(); reader.Close();

• video writer:

  ImageStreamWriter videoWriter = new VideoWriter("out.avi", new Size(1280, 1024));

  var image = new Bgr[1024, 1280]; videoWriter.Write(image.Lock()); //write a single frame

  videoWriter.Close();

• frame extraction:

  var reader = new FileCapture(fileName); reader.Open();

  reader.SaveFrames(outputDir, "{0}.jpg", (percentage) => { ((double)percentage).Progress(message: "Extracting video..."); });

  reader.Close();
